What Is Napa Cabbage?

Napa cabbage, known as hakusai in Japan, is a mild, tender cabbage commonly used in Japanese cooking. Compared to green cabbage, it has softer leaves, a sweeter flavor, and a juicy crunch that works beautifully in fresh salads.

Because of its delicate texture, napa cabbage absorbs dressings quickly while still maintaining its refreshing bite.

Tips for Success

Drain the Tuna Well - Removing excess liquid prevents the salad from becoming watery.

Don't Over-Massage the Cabbage - A gentle massage softens the leaves while preserving their crunch.

Chill Before Serving - A brief chill allows the flavors to meld together beautifully.

Adjust the Seasoning - Add extra soy sauce for a saltier flavor or a splash more vinegar for extra brightness.

Variations

Add Toasted Sesame Seeds - For extra nuttiness and texture.

Make It Spicy - Mix in a little Japanese chili oil or shichimi togarashi.

Add Corn - A popular Japanese combination that kids especially enjoy.

Include Cucumbers - Adds even more crunch and freshness.
